GASIFIER.

Patented Nov. 1221.

Application filed September 2, 1920. Serial No. 407,704.

To all whom it may concern:

Be it known that I, WILLIAM M. SUBLETTE, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements in aGaslher, of which the following is a specification.

The objects of this invention are, first,-to construct a gasifier thatcan be used in connection with any carbureter and any ignition system ofan internal combustion engine; second,to economize the consumption ofgasolene or similar fuels under any climatic conditions; third,to assistcarburetlon when the engine is cold, by a preheating process; fourth,toconstruct a gasifier that is simple, easy to manufacture, and automaticin operation. I

With the foregoing and other objects 1n View which will appear as thedescription proceeds, my invention resides in the comblnation of detailsand construction heremafter described and claimed.

I attain these objects by the illustration in the accompanying drawing,in which:

Figure 1 represents a part plan, and a part section on line BB of Fig.2.

Fig. 2 represents a section on line AA of Fig. 1.

Referring to the drawings in which like characters of referencedesignate similar parts, 1 represents the housing, the connection 19 isintegral with the top portion thereof, and the connection 20 is integralwith the bottom portion thereof, the combustion chamber 2 is circularlypositioned around the inner side of the said housing 1, the intake tube3 passes through the connection 20 into the center of the housing 1, thevalve chamber 4 is in turn adapted to lead from the said intake tube 3to the connection 19, the delivery chamber 15 is circularly positionedaround the intake tube 3 and the lower-inner portion of the combustionchamber 2, the port hole 14 is adapted to pass from the intake tube 3 tothe said delivery chamber 15, the delivery hole 12 is in turn adapted topass from the delivery chamber 15 to the combustion chamber 2, and thescreen 13 is positioned in the said delivery hole 12. A plurality ofexhaust tubes 10 are adapted to pass from the combustion chamber 2 tothe valve chamber 4, and the screens 11 are in turn positioned in thesaid exhaust tubes 10. The valve 5 is seated in the junction of the saidintake tube 3 and the valve chamber 4, a valve stem 1'? is integral withthe center portion of the valve 5, the spider 7 is seated inthe saidconnection 19 and is adapted to operatively re ceive the said valve,stem 17, the spring 8 is positioned between the said valve 5 and thespider-7, the slide 6 is operatively positioned in the intake tube 3 andis adjustably mounted on the said valve stem 17 by the nut 18. A sparkplug 9 is adapted to pass through the housing 1 to the said combustionchamber 2, and is adapted to connect in circuit with an ignition system,not shown, the connection 19 is secured to a manifold of aninternal'combustion engine, not shown, and the connection 20 is in turnsecured to a carbureter, not shown.

With the operation of my gasifier, the engme is first set into motion todraw vapor from carbureter, past the slide 6 into intake tube 3, thevapor is then adapted to lift the valve 5 in proportion to the suctiondeveloped by the said engine, against the tension of the spring 8, apredetermined amount of vapor is thus admitted from the said intake tube3 through the valve 5 into the valve chamber 4. A portion of the vaporadmitted into the said intake tube 3 passes through the port hole 14,into the delivery chamber 15, through the delivery hole 12, and screen13 respectively, into the combustion chamber 2, spark plug 9 isconnected to the ignition system to ignite the vapor within the saidcombustion chamber 2, the burnt gases are discharged through the exhausttubes 10, and the screen 11, into the said valve chamher 4, and is thenassimilated by the said vapor in the valve chamber 4, the said vapor isthus preheated by the said hot burnt gases to assist combustion whendelivered to the said engine. The delivery chamber 15 with the screen13, and the exhaust tubes 10 with the screens 11, are adapted to preventthe flame caused by the burning vapor in the combustion chamber 2 fromspreading into the intake tube 3, or the valve chamber 4.

As the engine increases its velocity and draws an increased flow ofvapor, valve'5 is adapted to be lifted into a more open position, andthe slide 6 is adapted to be closed thereby over the port hole 14, inproportion to the predetermined adjustment of the nut 18 on the valvestem 17, and when a full flow of vapor is attained the valve 5 is inlike manner held into its open position, and the slide 6 is closedtherewith to cut off the supply of vapor to the combustion chamber 2 andthe preheating process of my gasifier is thus discontinued.

While in the specification a preferred, construction is set forth indetail, still in practice such deviations from such detail may beresorted to as do not form a departure from the spirit of my invention.

Having thus described this invention, what is claimed is:

In a gasifier of the class described, adapted to be connected betweenthe carbureter and the intake manifold of an internal combustion engine,the combination of a combustion chamber with a firing means; an intaketube passing from the carbureter through said combustion chamber; avalve chamber connecting said intake tube with said manifold; a deliverychamber circularly positioned between the said intake tube and thecombustion chamber, adapted to admit vapor from the said intake tube tothe combustion chamber; an exhaust means leading from the saidcombustion chamber to the valve chamber, adapted to prevent the passageof fire therethrough; a valve means positioned within the said valvechamber, adapted to automatically open and close with the volume of gasvapor sucked therethrough; a slide operatively' positioned within thesaid intake tube, adapted to alternately close and open the port hole tothe said delivery chamber with the action of the said valve means as setforth.

In testimony whereoi I affix my signature.
